ACCELERATOR FOR AUTOMOBILES.

' Applicationfiled June 26,

To all whom it may concern:

Be it known that I, CHARLES L. MIToHELL, a citizen vof the UnitedStates, residing at Randolph, in the county of Cedar, State of Nebraska,have invented certain new and useful Improvements in Accelerators forAutomobiles; and I vdo hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to accelerators for automobiles. V I g j V Theobject of the invention is to provide a practical attachment forautomobiles which are not initially provided with accelerators. Thus,the embodiment which is hereinafter described is particularly adaptedfor attachment to a Ford car, so that it may be equipped with a footpedal accelerator in addition to the usual hand throttle lever.

WVith the above object in View, and such others relating to the detailsof construc tion, as may hereinafter appear, my invention will now befully set forth and described, reference being had to the accompanyingdrawings.

In the drawings Figure 1 is a perspective view of the attachment, thenecessary parts of the engine to show the application of the inventionbeing dotted in,

Fig. 2 is a plan view of the elements,

Fig. 3 is an elevation of another of the elements, and

Fig, 4 is a partial plan view of the attachment.

Referring more particularly to the drawings, 1 represents the engine,having the usual carbureter of a power plant; and the carbureter havingthe usual throttle arm. The steering post 4 carries the throttle rod inthe usual manner, terminating at its lower end in the right angularlyprojected arm 5.

To the above parts are connected the various elements of my invention. Astandard or rod 6 is mounted on the bottom structure of the automobileframe, and lies alongside the engine, so that its upper end may besecured to the latter by means of a clip 7 which is preferably connectedto one of the bolts of the water inlet connection. Upon the standardthus erected is mounted first an elongated sleeve 8 whose upper endprovides a seat for a collar 9. The collar is Specification of LettersPatent. Patented July 20, 1920.

formed of a coil of stiff wire, and at the upper end of thecoil the wireis extended tangentially of the coil to provide an arm 10, while at thelower end of the coil the wire is similarly projected to form an arm 11,which is disposed in substantially right angular relation to the arm 10.The arm 10 terminates in an eyelet in which is hooked oneend of a rod 12which replaces the usual connection between the throttle rod connectingarm 5, so that as the collar .9 is rotated, the throttle will beaccordingly moved. The arm 11 also terminates in an eye and re ceivestherein the hooked'end of a rod 13, which is provided at its upper endwith a foot pedal 14:, said rod 13 extending through a suitable aperturein the foot board of the car arranged alongside of the brake and clutchpedals. Also, the arm 11 is connected to a spring 15 which extends to' afixed portion of the engine or car body to normally retract the arm 11,so that the foot pedal 14 will stand in elevated position.

Also mounted upon the standard 6, so as to rest upon the collar coil 9,is a second collar 16, which is similarly formed of a coil of stiffwire, and the wire at the lower end of I the coil is extendedtangentially of the coil to provide a laterally and downwardly extendingfinger 17 which normally lies against the arm 10. The wire at the upperend of the collar 16 is extended at an acute angle in the generaldirection of the steering post to form an arm 18, which by means of alink 19 is operatively connected to the throttle rod connecting arm 5.Thus, when the hand throttle lever is operated, the collar 16 is rotatedthrough the link 19, and the finger 17 bearing against the arm 10 causesthe actuation of the throttle. However, when the foot pedal isdepressed, the collar 16 is not molested, since the arm 10 is free toleave the finger 17 upon its forward movement.

The operation of the foregoing mechanism is apparent from itsdescription, it being only necessary to note particularly the simplicityand effectiveness of the device and the fact that it is capable of beingattached to any car of the Ford type which is already in use, when it isdesired to equip the same with a foot accelerator.

What I claim as my invention is 1. An accelerator for automobilescomprising a standard adapted for securement adjacent the throttle rodconnecting arm of an engine structure, a length of Wire coiled on thestandard to form a sleeve and having connection for said second arm ofthe Wire,

a second length of Wire coiled on the standard to form a collar, one endof said coil being extended to form an arm adapted for connection Withthe throttle rod connecting arm and the other end of the'coil'beingextended and laterally turned to engage the first specified arm of thefirst named collar coil.

2. An attachment for automobile engines comprising a standard forengagement With the engine base and adapted for connection at its upperend With a portion of the engine, a sleeve disposed upon the lowerportion of the standard, a Wire helix rotatably encircling the standardand resting upon the sleeve and having its end portions con-v helixrotatably disposed upon the standard and resting upon the first helix,the lower end of the Wire or the second helix extending radiatingly fromthe helix against an arm of the first helix andzbetween it and the otherarm of the first helix; theupper end portion of the Wire of the secondhelix extending also radiatingly "from the helix and having a terminalhook for connection With the hand throttle rod of the engine.
